2. A student sets up the cardboard tube shown. The student holds the tube at an angle. The student drops a ball into each hole, then measures how fast the ball travels when it comes out of the tube.

• Hole 1, because the ball will have the most potential energy

• Hole 2, because the ball will have the most kinetic energy

• Hole 3, because the ball will have the least potential energy

• Hole 4, because the ball will have the least kinetic energy

3. A student pushed a rock from the top of a hill. What type of energy change occurred after the rock was pushed?

• Heat energy was converted to potential energy.

• Electrical energy was converted to heat energy.

• Potential energy was converted to kinetic energy.

• Kinetic energy was converted to electrical energy.

4. A pendulum swings between three positions, A, B, and C. The table gives the kinetic energy and potential energy of the pendulum at the three positions. Which statement best explains the relationship between kinetic energy and potential energy?

• The potential energy of the pendulum is always greater than its kinetic energy.

• The potential energy of the pendulum is always less than its kinetic energy.

• When potential energy increases, kinetic energy increases.

• When potential energy decreases, kinetic energy increases.

5. Thomas watches an orange fall from a tree to the ground.

Which best describes the flow of energy as the orange falls and hits the ground?

• Solar energy → Potential energy → Heat energy

• Potential energy → Sound energy → Heat energy

• Kinetic energy → Potential energy → Sound energy

• Potential energy → Kinetic energy → Sound energy

6. The diagram shows a ball at its starting position on top of a table. The ball rolls off the table and falls toward the ground. The graphs contain the potential energy (PE), kinetic energy (KE), and total energy (TE) of the ball. The total energy is the sum of the kinetic and potential energy of the ball. Which statement best describes the energy of the ball as seen in the diagram?

• The total energy changes as the ball moves from the table to the floor.

• Potential energy is stored when the ball is on the table and increases when it falls.

• Potential energy and kinetic energy change as the ball moves, but the total energy stays the same.

• Potential energy and kinetic energy stay the same when the ball is falling, but change when the ball is on the table.

• helium

• hydrogen

• oxygen

• 
  It used to be warmer.

• It used to be colder.

• It used to be in an ocean.

• It used to be in a desert.

• "Most volcanoes occur where two countries meet."

• "Most volcanoes occur where continents and the Pacific Ocean meet."

•
